These comparative views o f the model (at top) and real machine emphasise the accuracy o f our plan and Maurice Bodcy's workmanship. Fitted with two A.M.I5 engines driving pusher airscrews, the model is a first class performer. Perceptive readers will note that since the model was made, and before the lower picture was taken, G-APXK was re-sprayed with slight change to the nose colouring and a more simple Union Jack and company name.

To quote Ken: ,fIt is the most beautiful, complete highly pre-fabbed kit I have ever seen. The balsa is the best I have seen in a long time. The die cuts are clean and perfect. Finished nose blocks, leading and trailing edges, etc. Included are in. wheels, rudder and stab horns, finished landing gear with mounting nuts and bolts for engine, wheels, horns, etc., also aluminium spinner. In fact there isnothing to buy but the glue. As one fellow here put it, they couldn'tput glue in the box, because if the box got shook up too much the planewould be assembled . . .

Designing or building a model aeroplane, the ultimate performance will depend largely on the choice of Balsawood—what sizes for use for spars and load-carrying members, what grade to select for different parts. Balsa density can range from as low as 3-4 pounds per cubic foot up to 16 Ib./cu. ft. or more— a difference of 5 in weight factor for the same size stock. Obviously, therefore, choice of grade is vital as a means of weight control. Excess weight is paid for in loss of performance. The “ cut” of Balsa is also important in determining the stiffness or flexibility of sheet or strip. Stiffness is needed in spars, ribs, etc. Flexibility is needed in sheet for leading edge covering, or rolling into lubes for ‘"stick” fuselage or booms. You cannot afford to take chances with Balsa selection, which is why nearly all leading acromodellcrs specifically use SOLARBO. SOLAR BO BALSA is specifically selected and graded right from the start as raw lumber to suit acromodelling needs. Further skilled attention is given to fabricating this specially selected Balsa into standard sheet, strip and block sizes—and prefabricated parts for kit production. And if you want special grades sizes or “ cuts” , we are only too pleased to oblige.

I S T H E S T A R T I N G P O I N T F O R E V E R YM O D E L A I R C R A F T D E S I G N . . . ........... a n dyour automatic guarantee of top-quality material is to specify SOLARBO. Ask for SOLARBO BALSA by name—always. Your local model shop will have it in stock. Look for the name “ SOLARBO SATIN FINISH” stamped on every sheet. That is more than just a trade mark—it really describes the accuracy and smoothness of our cutting, achieved without fancy finishing treatments. The same standards apply to any piece of SOLARBO BALSA you buy.

I * fo r r . s . s . i i .Thanks to the generous response of the modelling

fraternity, The Model Trade Federation, individuals, clubs and the S.M.A.E. Area’s represented by team members, plus a handsome donation of £500 from the Society of British Aircraft Constructors, British participation in the World Control-line Championships at the beginning of September in Kiev, was assured.

Model Aeronautical Press Ltd., publishers of this magazine, donated £50 to the fund in keeping with their traditional practical assistance on the occasion of S.M.A.E. appeals.

Additionally, the editor accompanied the team in its travels via air and rail to the Ukranian capital and will provide a full report on the eventful meeting in our November issue.

Uo . . . on ll20 + I\aCI!If anyone had suggested water power for models a

couple of years ago we’d have thought him even more of a “wierdy” than most of us. Yet the water actuated silver Chloride cell is old stufT to many people in the electrical industry and such batteries have been put to many everyday uses.

Special units for electric powered free flight, produced by the Japanese Yuasa Company and the British McMurdo Company have been the subject of considerable experiments by ourselves and a resume of results is to be included in the 1962-63 A eromodf.ller Annual.

This is no doubt that in terms of power for weight, the Silver Chloride cell has no electrical match and despite the fact that the cells are not re-chargeable, it is possible to obtain a motor-running time/cost ratio equal to the accepted internal combustion engine or solid fuel reaction unit.

We have enjoyed the thrills of “discovering” electric power possibilities for over three years. Now\ the Sanwa “Electro”, as imported from Japan and distributed at Ripmax for 14s. lid . retail, brings this new field of aeromodclling to the inexperienced novice. Our tests have shown that this ready moulded expanded polystyrene model is capable of more satisfactory (and successful) flights than many other “beginner introductory” kits and in the hands of an experienced modeller can return flights of excellent duration.

Readers a re rem inded th a t special exem ption from the Ministry of Aviation is required for a irc ra ft models weighing over

11 lbs.

The batteries arc fitted, connected to the motor then injected (by eyedropper) with a 15 per cent, saltwater solution. Within seconds, the battery begins to give power. The model is then turned upright allowing excess water to drip away, and the motor will run for about 50 seconds, driving the little 4$ in. plastic prop at up to 3400 r.p.m. Thrust builds up for the first stage, then a flat power curve output gives steady climb.

We feel that the ”Electro” is likely to be the forerunner of many of its type.

C'liaiMO to nifM't the l ’ i lo i*The London Society of Air Britain, which has regular

monthly meetings at the Holborn Central Library, London, on the first Thursday of each month, will welcome aeromodelling visitors to their 7th Annual Test Pilots Forum on Thursday, 4th October, 7-9.45 p.m. Five famous test pilots will answer with skill and wit, questions of current aviation concern. From past experience of these meetings, we advise all scale enthusiasts with a flair for full-size interest to attend and sample L.S.A.B. activities. Another Air Britain item of importance is their second annual international recognition contest to be held on 20th October in Kensington, open to teams of three with trophies for the leading team and top scorer. Individual entries arc also eligible and details can be obtained from M. Hooks, 24 Brook Road, Thornton Heath.

I n o i l i e r S p h e r e » *

One is often tempted to reflect on events of a few years back and to wonder what happened to many of the famous names of aeromodclling which seem to have disappeared from the present day scene.

We were happily reminded of that A/2 champion from Germany, Rudolf Lindner, when we found that he has become German Open Class Sailplane Champion for 1962 in a Phoenix. This makes a great triumph for Rudi because he has now been twice world champion as a modeller and he has reached a peak in German full- size gliding.

We also read of 1 lenri StoufTs, who was leading Belgian in the 1962 Belgian Sailplane Championships, but actually placed 4th behind two Germans and a Dutchman in the open contest. Henri was, of course, well known for his magnificent efforts at pit-work for Ncri Bernard

483

in team racing and for his own acrobatic achievements at the various Critcrium of Europe meetings held at Brussels.

Then we were reading a strong editorial in the French magazine L' Air el L' lisp ace concerning the future of V.T.O.L. lighters and the issue of contracts for the future. Who was the author? None other than our old friend Jacques Morisset, that indefatigable French aeromodeller, fondly remembered by many British enthusiasts for his visits to this country on international occasions.

Continuing on the same theme, we are more than pleased to sec full credit given to Grahame K. Gates as Design Manager for the Beagle M.2I8 light twin which made so impressive a debut at the Farnborough Air Display. Quoted as “the most promising British light aeroplane for thirty years”, the M.218 is quite a contrast with Grahame’s enormous tailless gliders for which he is well-known.

Μ οιΙΗ Ιΐιικ* o f T a s teWe get many unusual enquiries for aircraft plans

from A e r o m o d e l l e r Plans Service. They range from scale drawings of miscellaneous types which are required for engineering departments to design new maintenance hangars, to manufacturers who have apparently lost their own records of what they have built in the past and, of course, we meet the constant demand of aviation historians. Late in May, wc had a unique request from Brion Clark, Patissicr of the May Fair Hotel, Berkeley Square, London. He had been commissioned to make a celebration cake on the occasion of the 30th anniversary' of United Arab Airlines. Could we please supply him with plans of the Dc Havilland Dragon and the De Havilland Comet airliner to common wingspan so that he could model them in marzipan and icing sugar ? This was no real problem for us, although, in fact, the two drawings are not included in our scale range. We were able to assist with sufficiently good enough details for Mr. Clark to produce the magnificent result pictured on this page. For those who like facts and figures, the cake weighed 60 lb., including 10 lb. of marzipan and 21 lb. of icing sugar. It took two weeks to make and was entirely designed and made by Brion Clark. What one might well term an edible masterpiece!

In d o o r W o r ld {'haiii| »io ii«lii|>KApparently ignored in the turmoil of the recent Radio

Control Championships, attention is now focused on the forthcoming World Indoor Champs, at R.A.F.

Cardington on September 22nd—23rd, 1962. Entries have been received from Finland, Germany, Hungary, U.S.A. and of course Great Britain, plus a lone entry from New Zealand to be proxy flown.

With all three members of the British team, Draper, Parham and Monks, achieving 30 minutes plus at the selection Trials, affairs seem all set for a memorable meeting, with probably all previous records “going for a burton.” (See report, page 487).

Interested spectators will be welcomed during the contest, but must produce their S.M.A.E. Membership Card to gain admittance. It is further stressed that the nature of the contest demands that everyone be prepared to move in slow motion (the draught created by quick walking can blow the covering completely from a model!)

Model on the Cover!PIAGGIOcontrol-line for tw o

W e k n o w fr o m our plans sales records that twin engined control line scale subjects arc favourites. Our range already includes a considerable variety, but demand existed for a more exotic type with ample flair for lavish decoration. We could think of no better subject than the Piaggio P.166 executive transport and commissioned Maurice Bodey to make this model from staff member W. Peter Holland’s design for a pair of 1.5 c.c. engines. Maurice has produced a real stunner and but for the fact that it ran into somebody clse’s accumulator at the Nationals, might well have been placed high at this year’s Championships.

Construction of the model has been kept as simple as possible, but special care must be taken in construction of Wing Spars and of the u/c units.

The 3/16 in. balsa fuselage keel is cut out to the shape shown on the plan. Mark on positions of Formers F5—F I5 and cut out slot in keel for pushrod. Cement Formers F5—F I5 to keel, followed by i in. balsa sheet bottom keel. Set aside to dry.

Thread f in. sq. hardwood bearers through F I—F5 and glue with Evo-Stick or some similar slow drying glue. (Note angle of F3). When set, cement to keels top and bottom. Check for correct alignment. Bend front U/C from 14 S.W.G. and bind and cement to bearers. Add Formers F2 and F4, plus top of formers F5-F15.

Wing spars W ll and W12 should now be cut from $ in. ply. Great care must be taken over these as the whole wing strength depends on them. When cut out, glue to respective positions on formers F8-F11. Cement ϋ in. sheet reinforcements pieces on F8 and FID in position on FI 1. Cut out fa in. ply bellcrank plates, drilling before finally cementing in place.Make cabin sides from fa in. sheet balsa with window positions cut out, and cement in place. (Do not fit windows yet).

P.IttGlcc.-2cc. engines

Bend main U/C leg from 14 S.W.G. and U/C stays, also from 14 S.W.G. Solder together as shown on plan. Bind all joints well with fuse wire first before soldering. Cut out the | in. ply plates A, B and C' and glue A and B together and assemble complete U/C to it, followed by Plate C. Use Fivo-Stick throughout. When completely dry, glue securely to F8 and 110.

Cut out all wing ribs and cement W1 and W2 into place on W ll and W12, followed by fa in. ply capping strips. Add W14 to W12, then cement W3-W6 on to spars and cement subsidiary spar W13 into place. Add remaining ribs W7-W10 ply capping strips and the -A-in. sheet balsa T.E.

Now turn to the nacelles. Use Evo-Stick on Engine bearers. Add 15 c.c. tanks, and also rolled paper lubes. Plank section between spars with fa in. and \ in. strips. The front intake and rear cowling blocks should be lightly glued and carved roughly to shape. Remove and hollow out, then cement firmly in place and sand to a smooth finish. Add the L.E. and tip tanks at this stage, then cover complete wings with fa in. sheet, not forgetting to feed lead-outs through ribs first. Note that wing sheeting enters into fuselage.

Bolt bellcrank into position and connect pushrod to it. The fuselage can now be planked in the usual manner. The nose block, cabin block, and tail block can be cemented into place and carved to shape. Sand complete fuselage to a smooth section.

The fin and rudder is made from two laminations of £ in. sheet and sanded to a symmetrical section. Then cut out slot to receive the tailplane. The tailplanc unit is made in the usual manner from two laminations of \ in. sheet, sanded to shape and cemented into place into slot in fin and rudder. Connect pushrod to elevator horn, in manner shown on plan. Make sure these joints are soldered well. Cut out the wheel-wells for main U/C and line the inside with thin card. Cut away planking for front U/C wheel-well. Give complete airframe a final sanding, obtaining the smoothest finish possible. The bottom of cowlings should be removed and the engines installed. Make cut-outs for cylinder heads and fuel needles, not forgetting to fuel-proof inside first.

Cover complete model with lightweight tissue and give two coats of clear dope, followed by at least three coats of sanding sealer until a satisfactory finish is obtained. Add final details such as U/C doors and tail skid.

Pli spray white, giving three coats and Humbrol Hi-GIo “Fire Orange” were used for the decor. Outline all Day-Glo with a thin black line. Add all cabin windows and windscreen, aerials, nose and tail lights etc.

The model should be flown with 8 in. x 6 in. pusher props. With two good 1-5 c.c. engines, good take-offs should be made without any trouble. Speeds of up to 60 m.p.h. can be attained and one engine flights made.

Fly the model on 50 ft. lines and test-fly in calm weather. All up weight is about 40 ozs.—and she lands absolutely beautifully on the stubby trike undercarriage —try it—you’ll like it!

T h e M f.r c o 49 is probably the finest British production engine which has appeared to date. Designed and developed to meet a specialised demand the price is high, hut it offers real “value for money" engineering throughout as well as achieving a top world class rating for power output. This latter claim is emphasised by the fact that it has achieved substantial success and recognition as a “first choice" power unit for R/C in the United States or the virtual “home" of the glow motor, and where so many excellent designs have been produced over a period of nearly two decades.

The Merco, of course, "borrows" many of the design layout features originated on the other side of the Atlantic for large glow motor layout, but it is essentially an original development from the “29" and “35" series and “engineered" on British lines. The result is a very sturdy motor but one which, because of its exceptional workmanship and linish, is extremely attractive in appearance and a precision engineers delight internally. The benefit of sturdy construction should be a long and consistent life, particularly with a ball race mounted shaft. The only penalty paid is in the matter of weight. The bare engine weighs 13 ounces which, although not

ENGINE ANALYSIS No. 100

MERCO 49 R/CWe celebrate a century of tests

with an outstanding productat all unreasonable, could materially shift the c.g. forward on a radio control design originally intended for a lighter power unit—e.g. a typical American "35" weighing 7-8 ounces. Conversely the modellers who always build tail-heavy in any case could find this a boon- but the man w ho gets down to optimum structural weights could find a shortening of the nose-length necessary to come out within the design c.g. range.

Despite being a large and extremely powerful engine the Merco "49" is extremely easy and safe to handle, with matching size propellers. Finger choking followed by a prime through the exhaust produces first or second flip starting from cold, with the needle at the running setting or opened up slightly. Re-starting when warm does not even require finger-choking, provided the fuel line has not drained empty. We found also that the Merco would start readily over a wide range of throttle settings, hot or cold.

Running adjustment is essentially non-critical and easy to establish. The actual setting depends on the fuel used. The Merco runs smoothly and well on straight fuel without marked deterioration of starling characteristics. For smoothest running and optimum performance, however, the addition of up to 5 per cent, nitromcthanc is recommended. This also appears to make adjustment of the throttle setting (barrel valve stop) and air bleed (idling mixture jet) less critical for maintaining minimum r.p.m. One can play about with the low speed settings, using various combinations of the barrel stop and air bleed adjustment. From a normal load-speed of 10-11,(XX) r.p.m., slow running can be held consistently at about 2.500. A slightly higher igurc e.g. approaching 3,(XX) r.p.m. would probably be safer for Hying, however.

The one important over-riding adjustment is a slightly rich setting on the main needle. Extreme low running speeds arc not necessary for flying and the few hundred r.p.m. which may make all the difference between a critical adjustment and one which is consistently reliable will not materially affect flight performance. Any propeller which normally revs at 10,000 r.p.m. and is slowed to 3,000 r.p.m. will have lost much of its thrust and will act as a pretty efficient brake in a dive.

The multi-speed performance of the Merco 49 is not so completely worked out that it could be classified as foolproof. It does need careful adjustment and the suction lift seems to become a little “marginal" at low speeds. Tank position, therefore, can be important and should be selected to suit low speed running. A pressurised tank seems to upset things completely, making adjustment very sensitive. On the other hand, we arc satisfied that if trouble does occur in flight—e.g. the engine stopping in the air—the cause is not in the throttle design but (/) incorrect adjustment of the two low'-specd controls (or too lean a main mixture setting); (#7) unsuitable tank positioning; or (Hi) an unsuitable plug. The makers specifically recommend a shielded type glow plug for multi-speed use.

On test, the Merco "49" peaked at around 12,000 r.p.m., with a corresponding B.H.P. figure slightly

in excess of .7. The power curve is extremely flat and an interesting characteristic—for a glow motor, at least— is the high and sustained torque developed at lower r.p.m. figures. Nylon propellers are a logical—and safer—choice for a motor of this potential, and confined virtually to one size—12 x 6. This size produces a static r.p.m. figure of 10,000 on 5 per cent, nitro fuel, which means that the “ unloaded” figure in flight will be slightly lower than the peak. Most of the radio flyers appear to have adopted the 12 x 6 prop, as standard, although 1 1 x 6 could equally well be used to develop true peak r.p.m. in the air, and may be preferred for control line. 12x5 and 1 2 x 6 are other possible sizes for free flight, pulling the operating r.p.m. down but still remaining on the flattish part of the power curve. Larger diameter sizes do pull the r.p.m. down rather a lot. Any smaller propeller diameter than 11 inches makes one approach hand starting with exaggerated caution!

The combination of ringed piston and ball race mounted crankshaft results in an engine which appears to need very little running-in time. The maker's mention one hour, and not leaning out the mixture completely for the first 30 minutes. On the particular specimen we had (and which had experienced little or no previous running) only ten minutes running-in was more than adequate and there was no further detectable change in performance after this time, over a final total of two or more hours. There was no evidence of tightness of slowing up or overheating. This seems to confirm running-in practice established by a leading American modeller for the Merco—15 minutes on the bench and then into the model. This same modeller also mentions that a comparable (American) glow motor takes so long to run in properly that the cost of fuel during running in exceeds that of the actual mtoor! The Merco appears entirely free from any criticism of this sort.

Dcsignwise the Merco ”49” employs orthodox large glow motor layout with opposed transfer and exhaust, and orthodox crankshaft rotary valve induction and timing. The crankcase casting consists of an exceptionally

clean and well finished pressure die-casting in light alloy, incorporating lower cylinder housing, intake stub and ball race housings. A hardened steel 1 in. o/d liner with a flanged top plugs into the lower cylinder casing and is positioned vertically by a turned finned jacket. When the head is in position and tightened down with screws the liner is thus positioned by the depth of the jacket, tightened up against the bottom of the liner flange. Three long screws extend down into the crankcase unit, with three further screws attaching the head to the jacket. The bottom of the jacket itself seats on a thin paper gasket. The cylinder is slightly offset laterally (Desaxe), which is a design characteristic of all the Merco scries; this arrangement giving certain theoretical advantages.

Ports cut in the liner walls consist of four cqui-spaced square holes for the transfer and four similar sizes square holes, spaced apart in pairs, for the exhaust. Transfer and exhaust have substantial overlap. Port areas are relatively small and the use of a scries of separate port openings rather than a single port each side is dictated by the necessity of maintaining a satisfactory unbroken rubbing surface area to avoid trapping the piston rings. The transfer passage way itself is incorporated in the main casting and docs not require an additional piston port to open.

The piston of light alloy, grooved to accommodate two cast iron rings and shaped with a filleted deflector

A 31 inch wingspan all sheet balsa model for free-flight (or R /C ) by C L IF F W A L K E R

“ J I N T Y ” w a s d e s i g n e d , as is known in Yorkshire, as a “Chuck-a-baht”. This is an extra model to carry when out on a day's flying, and to be used as a relaxation model (a) at the end of the day, (b) should one prang the larger models, or (c) the queue is too long for radio.

The requirements for this type of model arc: dimensions such that the model will lit into the boot of the car, along with picnic basket, folding chairs and what have you, a fuselage capable of taking lightweight radio should the model prove suitable, tough and, above all, easy and quick to build.

“JINTY” is the latest in a scries designed and built over one weekend, looks like an aeroplane and is a really good performer. Interested?—then have a go, you will enjoy making it.

The original has a Mills .75 engine fitted with three- bladed prop; but any engine up to .8 would be suitable.

Straight-forward fuselage construction calls for pre- cementing engine bearers to suit your engine. Stitch on the front u/c leg and well cement. Assemble the fuselage frame on its back, over the plan. Use a couple of clothes pegs to nip sides to engine bearers until set. When set, add nose doublers, bottom planking, wing dowels, and till in fuselage nose. Lay on to i sheet, draw round fuselage for top deck with sharp pencil. Cut slightly larger. Cut slot in deck to receive fin. Sand roughly to shape. Pre-cement and fix firmly on fuselage. Sand off to fuselage with nice rounded curves. Fit fin; this docs not require an anti-warp strip as the slot in the deck takes care of this, but don’t be lazy here and omit the trim tab. as this is really useful.

Wings are all sheet construction. Build in two halves, cut w ing strakes to shape but do not stick the joint yet. Pin ribs over plan, placing pins to the rear of the ribs. Cement on the front 3 in. strip, pinning through both the sheet and ribs into the board. Remove rear pins— cement trailing edge strips, pre-cementing joint-pin down. Notice that all the ribs are the same size and the wing tip rib is now protruding well beyond the tip T/E. Fake the wing from the board and cut the tip rib flush with T/E, sand the underside of the rib till it meets T/E. You now have a half wing with a natural wash in at the tip—a great asset. Complete the other half. Bring the two half wing joints together, having placed 3 in. packing under the tips, and you will find they only touch towards the middle. Use a sanding block on the high spots each joint until they fit. Pre-cement and fix. Leave to dry well with dihedral packings still in place. When dry, cement well underneath the dihedral joint, and sheet between the first wing bays. This gives a platform for wing bands. Finally, dope on a 2 in. wide piece of fine linen around the joint for extra strength. The tailplane is a sheet shape with anti-warp strips.

Undercarriage is simple, but very efficient and virtually crash-proof. Don't alter its position as it gives a perfect take-off. For fixing, use one rubber band from each wing dowel, stretched round the U/C yoke and dowel twice.

Sandpaper all components and cover with lightweight tissue doped on. Sand lightly. Give two coats of Butyrate dope and sand between each coat. 1 emphasise the sand because that is the difference between a good smooth finish and a daub. Decor to suit yourself. The prototype model was coloured red, and for speed the decor was effected in silver metal tape.

Test for glide in the usual manner; if you have the C.G. to plan position then it should be satisfactory; if not, the tailplane may be packed with thin balsa. Now here is the important part; bend the trim tab about l in. to the left, this is a safety precaution as with most free flight low wings, a right turn under full power will build up into a spin; on the other hand you can trim to

available on th e m a rk e t" scale items

W h e n i n M a r c h 1957 we published drawings for Brian Sichi’s Sopwith 1£ Strutter, it was classed as a semi-scale, due to the fuselage planform, wing section, and the lack of scale type wheels. Normal airwhecls were used at the time as the best available means for a soft landing on a rigid faired undercarriage. However, when a second 60 in. R/C version of the Π Strutter was built, Brian was determined not to use the usual all ply or ply disc and solid rubber method for the wheels. He therefore developed a modification for a pair of Keilkraft 3* in. airwhecls, as detailed here. The final scale appearance is good and there is the facility of tyres. It is also nice to know that when you launch 4—6 lbs. of model it will have the cushioning cfTcct of scale type airwhecls.

In making the modification the only difficulty for the average modeller may be in obtaining the use of a Lathe to turn the metal wheel hubs, for which the use of i in. or 5/16 in. dia. dural bolts and nuts, turned and drilled is advocated. Otherwise anyone who has a Wolf Cub or similar drill with an Arbor Assembly, and a few sharp chisels can turn the wheel discs from $ in.—$ in. hard multi-ply. The latter is indeed a most enjoyable part of the job.

After painting the discs, assembly is as usual for airwhecls, although a little care is required to line up the valve hole with the i in. hole in the inside disc. This done, the discs arc slowly pressed together, the hub and collar fitted and screwed up tight. Provided really hard ply is used, (if the discs arc to be made from wood) the wheels will give no trouble at all.

World NewsF i n a n c i a l c o n s i d l r a t i o n s affected attendance at the World Championships for control line models due to costly travel to Kiev, U.S.S.R. However, last minute information lists thirteen Nations in attendance, and these include U.S.A., Belgium, Italy, Finland and of course G. Britain. Not all could field a full team. The U.S.A. which originally elected to cut team race participation, made a change so that the successful Nats Champs Stockton and Jehlik could attend. Italy despatched only speed men, referred to as the Super ligrc Squadrc and not including record holder and National Champion Ugo Rossi! Conversely, Belgium had her speedsters on the short list and would only have sent them if finances materialised. Interesting teaser is that from all available information, G. Britain had fastest team race times in all the team selection trials, and was well up in speed. Next month we'll have the full low-down on what happened . . . if they let the Ed out!

Over in Brazil, the Associacao Brasilieira de Aero- modelismo was beset by appalling weather for the 4th S. American Championships. It was cold and windy! Definitely not the average European’s picture of Brazilian

conditions! Anyway, advance news gives an Argentinian victory to Jorge Cea in speed at 105 m.p.h. with S/Tigre G.20, and the Leys brothers at 6:23 with Oliver Tiger in T/R. Brazil won stunt, with Cezar Gama's Fox 35- Thunderbirdy Walter Nutini took Wakefield, a scant 4 secs ahead of the Argentine’s Colombo, and Kiuoshi Vcno took both F/F power and R/C (using all-Japanese equipment). Honours were spread further by Miguel Quartino of Uruguay taking the A/2 event. Pictures next month. These S.A. Champs are the nearest approach to the oft suggested “World Regional’’ meetings. They serve to stimulate contest standards, though perhaps not to the same extent as the World Champs; but are also a solution to the high cost of team travel.

A longer established and similar meeting is the annual Nordic Countries Champs which many modellers will imagine is restricted to free flight. Not so, for the 2nd control-line champs took place at Helsinki on August 4lh-5th. On a points basis, the hosts, Finland came out top, ahead of Sweden and Norway, and this was largely due to their sweeping 1, 2, 3, victory in stunt by Kari and the two Sundell Bros, and a 1st and 2nd in speed by Valo and K. Jaaskclaincn. Sweden’s Roscnlund and Bjork were not up to their usual performance in team racing but managed fastest heat time of 4:56 and won the final at 5:04 to add another honour on Miss F.A.I' already long list. Denmark did not participate this year and Norway sent only stunt men, with Birger Bulukin (Nordic F/F power Champ) taking a 6th place. Either Norway or Denmark will stage next year's event; but not, we imagine on the runway of the National Airport as the Finns were able to fix this time. We hasten to add that it was a brand new, as yet unused runway too!

Over in Australia, we understand that the Merco engines have gained a real grip on the stunt fraternity, with 1st, 2nd, 4th and 6th in the Victorian State Champs. In free flight, Ralph Kenyon won Wakefield with a perfect 900 score, and Cox engines took first three places in Class 1 power ratio. Best was Brian Laughtons ratio of 26.91:1 with a Cox .051. Incidentally, when reporting the Aussie Nats earlier this year we mixed their glider events. They have F.A.I. sailplane (won, as we said, by Scan O’Connor) and A/2 run separately, won by Brian Amey, a gent who, when occasion demands, can leap two four foot barbed wire fences and a car bonnet with the model still safely in fowl Quite a Kangaramey!Heading.

Some “ sights of the World” geographical books carry pictures of the “Valley of a thousand Hills” in Natal, S. Africa, It is a sight. Also a fright, when close to the S.A. Nats, and collecting lost models. Brian Partridge from Jo’burg was in the lead for ΑΛ when he dropped in the hills, so did Pete Visser, who was lucky to locale and won by a 4th flight. Pete’s all sheet surface Texan proved the answer to rain damp, and his A/2's went well to carry off that event as well. “Cookie” Watt took Wakefield, and he also went along with Brian Partridge to the Rhodesian Nats, and between them they won all the free flight events.

Without doubt, the momentous news on the month comes from the Li.S.A. Nats, held at Glenview Naval Air Station at the end of July. Pages following give an insight into the most impressive event, for scale models, and we shall be carrying on with model details next month. Our reporters on the spot tell of jet flying at 02:48 a.m., of many tyre and u/c failures when the “heavy” C/L scale models d.inked back on terra firma, of a 72 in. rotor scale multi channel radio controlled Bensen Gyrocopter with Merco 35 and of a scale type which few had heard of simply because it started as a model, and will be scaled up for full size production as the Jeep-O-Plane with rumoured 14 million dollar backing. Such is America! Pictures next month of these, and also of some strikingly novel free flightcrs. Bill Wcrwage notched yet another Nats victory in stunt with his Fox 35 Ares (and collecicd a hundred dollar bonus from Ambroid in ihe bargain!). Dr. Ralph Brooke and his Orbit equipped Veco 45 Whistler was stated by some to be smoothest of all the multi men, and moreover, along with Ed. Kazmirski flying Taurus as detailed in October R.C.M. & E. and Jerry Nelson with his Sultan makes up the 1963 World Champs R/C team to go to Genk, Belgium next time. 167 entered multi, order by the week-end was Kaz Nelson, Zcl Ritchie (with a Sultan and his own Space Control system) Brooke, Les Fruh and Hal Dc Bolt. Top 15 then flew to select the team and only Ritchie slipped a place. Top five used Veco 45, trike gear and full span strip ailerons.

ing line tension, hence the 5 deg. forward sweep to the wing. (A fuller explanation of this point is provided in the Monoiine Speedmastcr Unit instruction leaflet.) Do not be alarmed by the large amounts of inset shown on the plan, there is no tendency for the model to “come-in” , and it can be flown in high winds in complete safety— the design possesses a marked “grooving” stability.

To start construction, the engine should be mounted in the pan using 4 It.A. screws and incorporating 2 deg. right thrust. Engine mounting lugs will protrude slightly over the edges of the pan and should be filed flush with the sides. It will be noted from the plan that the McCoy prop, driver is discarded and a one-piece driver/spinner backplate fitted in its place, the Pomadi speed pans are cast to fit this modification, which reduces the shaft overhang on the bearings by % in. and provides a sturdy assembly which will stand the loads imposed by a mechanical starter. The spinner itself is a cut down Vcco Needlenosc 2in.. and fits the propcllor nut with the stud provided, the driver is a simple turning job and keys on to the shaft in the same w'ay as the original. Cut the fuselage crutch from a I in. plank of hardwood, preferably of close, straight grain (pine, deal, or passwood if available) and shape and hollow out so that it is a snug fit over the engine and will contain a pen bladder tank, containing 50-60 c.c.'s of fuel, at the same time keeping a good wall thickness, particularly where the hold-down bolls and locating studs fit to the pan. Recess the wing and tail positions in the crutch, being careful to maintain zero/zero incidence, there should be at least } in. depth below the wing or the control unit may foul the car-

Invaluable lips on an approach to speed * ^ · * ^ ν* Hying as loldloRalphhould by (.usjohnson

As λ n e w c o m e r to speed flying, l naturally looked for a successful design before progressing from “29” to “60“ models. Gus Johnson's original black painted Ginmill is now a familiar sight to most speed fliers in this country, and when I say “original” it must be appreciated that this model is seven years old and has been a consistent and regular contest winner since the original conception of the design in 1954. Some notable official speeds are 155 m.p.h. at the 1954 Tampa, Florida, Jubilee, 160 m.p.h. at the Florida State Championships, 157 m.p.h. at the 1958 King Orange internationals, 156 m.p.h. at the 1960 British Nationals and 160.9 m.p.h. at the 1961 British Nationals, most of this achieved incidentally, with the same engine. Obviously, the model is a formidable contest design.

The model is designed around the McCoy “60”, scries 20 racing engine mounted in an aluminium half-pan (available from Paul Pomadi of Nuneaton); is built almost entirely from hardwood and incorporates the Stanzel Monoline system; it is rigged to fly in a clockwise direction and is aerodynamical ly set up for “circular flight” as a glance at the plan will indicate. This is achieved by engine, cowl and fin inset, wash-out and wash-in in the wing panels and forward sweep of the wing. A simple explanation of this set-up is as follows: The model flies in a clockwise direction to utilise the engine torque in the critical take-off stage, helping to keep it on a tight line. At speed, the offsets partly balance the effects of centrifugal force and torque, and in consequence, heavy line tension is avoided. This allows engine power to be utilised to the full with minimum drag from the airframe which would otherwise be flying slightly "nose out” or at an angle to the relative airflow. The Monoiine system, with its greatly reduced line-drag, permits a forward pivot point with the model maintain-

burettor venturi when the model is assembled. Cut the air duct in the left hand side of the crutch, just ahead of the hold down bolt opposite the carb. and angled forward slightly and flush with the outside of the model; this ensures a continuous supply of fresh air for the engine without any ramming effect.

Cut and sand the tailplane and elevator from l in. 5-ply, assemble with good quality linen hinges and a small brass bush either side of the horn for smooth operation. A small Vcco horn, or one made up similar, is ideal for the job—preferably silver soldered or brazed, a failure of this component would be disastrous.

The wing, probably the most important component contributing to the successful performance of the model, should be carefully marked out on a blank and carved and sanded to the section on the plan. Draw the outline and mark plainly top and bottom to avoid confusion, before drawing in the 40 per cent, chord maximum camber line on the top side and 50 per cent, maximum camber line on the bottom. At the root section, draw a line i in. from the bottom of the blank to ·& in. at the tip to indicate the leading and trailing edges, then adjust the trailing edge lines at the tips, using a protractor, to give 2 deg. wash-in on the left and 2° wash-out on the right panel. Cut away L.E. for the Monoiine unit installation and tack cement back in place before carving and sanding the wing to section, noting that the leading edge is not sharp but has a diameter of -fo in. to & in., and the wing profiles are smooth arcs throughout. After shaping, install the control unit and tip guide tube, ensuring that the unit is completely free and does not bind and that the control line can be attached and removed easily. Temporarily fit the wing and tailplane and link up the controls with the 16 S.W.G. push rod and its supporting push, making sure that the controls

snap back to neutral after operation up and down.Carve the cowl from laminations of hard balsa and

assemble round the engine and crutch so that the whole top half will slide on and off with case. The cylinder head is left exposed for cooling, and the top lamination of the cowl should be a snug til around it for maximum efficiency. Note the comparative sizes of the inlet and exit air passages of the cowl, ihcsc arc important to maintain the correct working temperature of the engine. Finally, attach the cowl with right rotation about the axis of the engine cylinder.

Carve the top and bottom rear fuselage blocks and shape the plyw'ood tin, then roughly assemble the model to check the balance. If this is badly out of place, reposition the wing accordingly before the final assembly; the model should balance at the control unit. Fillet the wing and tail to fuselage joints with plastic wood or soft balsa, then reinforce with gauze and cement before grain filling and painting. Final finish is up to the individual builder, a glass-like finish is not essential, rather aim to get a smooth continuous surface with wet and dry paper and soapy water, before polishing with Brasso. A solid fuel proof finish should be used or the model will soon look very “second hand" at least 10 coats of fuel proof paint should be used to resist the powerful action of hot fuel.

The dolly is a simple structure of 10 and 12 S.W.G. wire, but remembering that the success of every flight depends upon its efficient working, some care should be taken to ensure that the model fits snugly in the cradles and wing rests, and that it tracks correctly holding the model at zero angle of attack. Use good quality wheels that won’t throw their tyres at high speed, if disc wheels with solid rubber tyres are used, it is advisable to wire the tyres to the hubs, and also to bind the inside wheel treads with smooth tape so that it will slide if the dolly does go oil' track. A 4 oz. weight is attached firmly to the outside leg to prevent tipping and gives the whole assembly some “ feel" until flying speed is reached. Final assembly point of the dolly is the centre pin of 12 s.w.g. wire that slips loosely into the pan as close as possible to the back of the engine; before soldering this pin, the following check for the correct rig of the dolly should be made. Put the model in the dolly and hook up the linePicture opposite shows a u th o r Ralph Gould (je t flying in s tru c to r in R.A.F.) w ith his C inm ill. made under th e guidance of Major Gus Johnson, U.S.A.F.

and handle as though to fly, then try to pull the model round as for take off. If the tail wheel pulls in, move the pin forsvard. or back if the main wheels pull in until the dolly will remain squarely on the line, then permanently solder the pin in place. The lc*ngth of the pin should be approximately Ij in.

Flying-Assuming that the intending builder has at least

flown a Monoline trainer, no great difficulty should be experienced in Hying the Cinmill, provided that the basic differences between Monoline and two-line control are fully appreciated. It must be remembered that Monoline is trimming control fitted to a basically stable speed model, and full up and down obtainable so easily with two lines is seldom used, except to damp out an oscillation. There is a slight lag in Monolinc control, but once this has been experienced and necessary anticipation applied, the control system is quite positive.

Start the take-off run pointed downwind and hold the model on the dolly with neutral or slightly down elevator until flying speed is reached, usually alter a 1 lap slight up elevator will then unstick the model and down must be applied immediately to correct the climbing attitude. As the model comes back to level flight, neutralise the control knob then trim it out as it accelerates to top speed. Acceleration as the model leaves the dolly is very good, and the model must be brought back to level flight as quickly as possible before an oscillation starts (which no amount of up elevator will stop on the downhill plunge). Once in the “groove" the Cinmill should fly “hands-off". Gus learned to fly Monolinc with a hand launched “60" model, so why not give it a try— it's definitely faster than two lines and under present S.M.A.E. line rulings, there arc no minimum line diameters imposed as there are in America; A.M.A. rules require .028 in. line, in this country .020 in. or .022 in. should be adequately strong and faster.IrIiiiiiIIIFull size copies ofth is l/5 th scale _______ ___ ____ „re p ro d u c tio n a re available from . ,A.P.S. p rice 5/6d. \ \i n c l u d i n g postage.

ability, and round trips exceeding 8,000 miles have frequently been made. Prototype installations of the externally carried missiles have been made on XH 563, which went to the United States for inspection by engineers at the Douglas Aircraft Co. for adaptation to carry two Douglas Skybolts and XH 539 has been carrying the first Avro Blue Steel stand-ofT bomb.

The Vulcan has demonstrated its extremely high performance in take-off, climb and manoeuvreability wherever it has been displayed and this has been particularly impressive to those who have seen “scramble” take-offs during military exercises. It is a complex weapon system capable of flying very close to the speed of sound, above 50,000 ft. altitude and has an excellent maintenance record. A point which may not be generally realized is that it actually carries five jet engines, the extra one being a 90 h.p. Rover gas turbine unit used as a generator for the many ancilliary systems (there are more than 100 electronic motors and actuators). This is buried within the wing as an auxiliary power unit. From the modelling aspect, (he wing sections are of special interest and may possibly inspire new thought in the design of model free flight Deltas.

AEROPLANE IN OUTLINE No. 64

AVRO VULCAN B.2

B r i t a i n ' s f i r s t bomber to be specifically designed for carrying a stand-ofT bomb or large air-launched ballistic missile, the Avro Vulcan B.2, is now well established in Squadron Service. The Commanding Officer's aircraft of No. 27 Squadron is illustrated in our 3-view drawing and another Squadron, the first in fact, to receive the Avro Vulcan Mark I and also the Mark II, is No. 83. Each of these Squadrons is based at R.A.F. Scampton.

Externally, an immediate recognition feature of the Mark II is its lower set nose due to the shorter nose wheel leg, which brings the fuselage almost parallel to the ground line. Closer examination will show the increase of wingspan by 12 feet and the change in the control system. Whereas on the Mark la conventional aileron and elevator system was employed, the Mark II uses elevons. This is to remove aerodynamic buffet limitations and enables the aircraft to take advantage eventually equipped with the 20,0001b. thrust Olympus first verions being produced with the 17,OCX) lb. Olympus as compared with the Mark I’s 13,500 thrust jets.

The bulged rear fuselage extension with electronic counter-measures equipment, which first appeared on the Mark IA, is now a standard feature of the B.2 and also the flat aerial plate which bridges the gap between the starboard jet nacelles. Fitted for in-flight refuelling, the Vulcan B.2 has an extreme long distance cap-

F i r s t c l a i m a n t t o correctly identify 3 tins bearing the name of a famous Tobacco brand and containing modelling gear and tools will have his goods returned by N. P. Nielson of 90 Copse Avenue, West wick Lane. Kent, who found them near the C/L circuits at the Nats! Item for a ll to note is that the 1962 South Coast Gala is cance lled . Efforts to find a suitable airbed have been unsuccessful and rather than use an inferior place, they’ve decided to cancel.

Proposed site for the S. EASTERN AREA Slope Soaring meeting in November, is at the well known landmark the Wilmington “Giant” just otf the Λ27 between Polegate and Lewes, a first class site with almost 360 deg. faces, so it is claimed in “S e a d o g .” Must be a task to get to the lop!!

John West o f Brighton D.M.A.C. followed up his success in the Shelley by winning the Power at Northern Heights, the Surbiton Gala and Devon Rally, and Ken Winstanlcy won the Glider at the Surbiton Rally while Fred Boxall was placed fourth in the Rubber. It is also confirmed that John West flying a M e r c u r y M e n to r won the Gamage Cup, and that Dennis Latter and Ken Winstanlcy came second and third in the Pilcher Cup—good going by the south coasters!

In LONDON AREA, the 1962 Blackhcath Gala will be held ut Chobham Common on October 21st. Flying commences at 10.00 a.m. and contests arc for U/R Rubber. Power and Glider. Entries will be Is. 6d. For further details contact P. Crosslcy, 11, Broadficld Road, Catford, London. S.E.6.

Hayes M.A.C. Rally will be on October 7'.h at Chobham Common. Classes to be flown will be Glider, Rubber. Power and iA Power. In the first round of the LONDON AREA Knock-out Comp. Hayes team (Rubber, Power and Glider) won against Springpark, but it was a hollow victory as the opponents could only raise two models with which they turned in far better times.

A lot of 4 A Team-racing activity is evident at the present time, the most popular motor is the Oliver Cub. At the last S.M.A.E. speed meet at Oakington, the K. Lindsey—G. Copcman group placed in F.A.I. Class, and J. Taylor placed in Class 2 and 3. Kevin Lindsey’s R o s s i V u lcan Jet entry struck fuel trouble in the shape of a quart can standing on the tarmac, this has temporarily silenced it.

The Club has put on two displays, one at the National Physical Laboratory, one at the Thames Valley Grammar School where they had an audience of around 1500 to sec a Speed flight o f near 150 m.p.h. with a McCoy 60, a precise stunt exhibition by Jeep Newman. Combat, and a six in a circle finale with an obstacle course. They had the aid of the Felt ham. Kenton and Northwood Clubs and hope to provide a few pounds towards the cost of sending the British C/L Team to Kiev—£8 in fact.

The Hayes Circuit, Charville Lane was officially opened on Saturday July 28th at 2.30 p.m. by Councillor Burke, the Chairman of the Council. Members of Feltham, Northwood, Kenton and Esher clubs also took part. Rather fortuitously, the first official flight, by John Taylor o f Hayes, was the fastest ever recorded by a Hayes model. 147 m.p.h. with a McCoy 60-20 job swinging a hard-carved 8 x 13 in. Maple prop. Altogether, Speed, Stunt, team race. Combat, Scale and sport-type models were demonstrated.

Cosmo A.C. demonstration team have performed twice recently. Once for the Meophain Scouts Camp Day and another for A.E.L Ltd.’s Gala Day.

In the latter, the normal schedule was changed so as to include a demonstration of One pilot flying two models, by Stan Robinson. This proved to be highly successful and entertaining.

Aubrey Tick, is experimenting with a 61 in. span stunt model of 660 sq. ins. area. It has a detachable nose so that various engines can be fitted. Although designed primarily for an Oliver Tiger 2.5 c.c engine it is hoped soon to be powered by an E.D. Super Fury 1.5 c.c. engine, since the model has a very light wing loading of 6 ozs. per square fool.

Wanstead A.C. have decided to split their rally over two dates. First, for Class B combat and B T R will be November 4th. More details later. Contest minded modellers will be welcome new members

contact D. J. Bolt. 14 Marston Road, Ilford. They amuse themselves at club meetings with Cox .010 R.T.P. 100 lap Rat Racing (one stop compulsory). Models have to be flown one at a time for safety.

Owing to growing crops Dobdenairs M.F.C. club F /F comps have had to be postponed, but they should be under way again by September 2nd, when several “ G a rter K n ig h ts” will be in attendance. Things being very quiet lately, it was decided to hold a display in the local library foyer with the kind co-operation of the librarian, together with his books on flying subjects, including several recent issues on modelling topics and photos on loan. This has been tied up with reports and photos in two of the local papers

Mike Burrows of St. Albans won the Pilcher Cup and was also 2nd in the Open Glider at Surbiton. Devon Gala was attended by a few members and there, Mike Burrows flew a rubber powered h e lic o p te r in the open rubber event but lost it after staying in sight for 2 mins 8 secs! Latest models on the build arc two Autogyros, one for .5 c.c. and I c.c. and yet another head skinning C h a ry b d is (large) for 3.5 c.c.

The free flight lads have had a good time of it lately, four Whitefield members flew for the NORTH WESTERN AREA in the recent Champs and took 2nd. 3rd and 5th Power places at the Rush Trophy, Toolan and Hailey (5th and 2nd) both using D ix ie la n d ers with o f f s e t pylons and Day Glo colour schemes. No trimming troubles with this oft-set and the Day Glo patches arc a boon for spotting in com. F a rm e rs w ill a lw a ys retrieve, they find, i f you show them where the model is. Local Gala at Prestwich saw the control-line boys in action for two half hour demonstrations. It’s the one time of the year when John Citizen likes big noisy motors, and a small well drilled team of control-line flyers can really fetch the crowd around the circuit. Using a Gala as a sort of extra club meeting w ith higglcdy pigglcdy flying is a waste of time, and boring for the spectators. Take a lip, get a small team, fly :o a pattern for J un hour, and finish with eve ryb o d y in the middle.

Λ model club has bscn formed at R.A.F. Wilms low in Cheshire, and extends an invitation to all civilian model fans in the Area. Present membership is ten, all of whom are extremely keen, with two large rooms at their disposal, where they can build day and night, and run engines until .hey melt, without any interference! Contact CpI. Johnson, 27 Tudor Road, A.M .Q., R.A.F. Wilmslow.

An exhibition of models is being organised by the South Manchester Model Group and is to be held in the Stamford Hall, Altrincham,

Merco 49 R/C test (cont. from p. 491)on top. The \ in. diameter fully floating gudgeon pin is hollow and fitted with aluminium end pads. Piston walls are quite substantial and total weight of the piston plus rings is a little under jj ounce. The gudgeon pin is of hardened steel, ground and honed to finish. The connecting rod is a forging in light alloy with plain bearings and drilled with lubricating holes at each end.

The £ in. diameter crankshaft is turned from ΕΝ.1Λ steel, case hardened, ground and line-finished. The crank web is cut away for counterbalance and the solid crankpin is \ in. diameter. The \ in. diameter length is maintained up to the front bearing, where it steps down to 315 in. diameter (8 mm.) and thence (outside the bearing) to the 1 in. diameter threaded propeller shaft. The dural prop, driver is secured by a split steel collet on the 8 mm. length of shaft protruding from the front bearing. Both races arc S.K.F. high-speed type. Shaft port is rectangular, approximately A in. x f in., opening into a 1 in. diameter central hole.

The carburettor unit is fabricated in dural and consists of a body unit plugging into the stub intake in the crankcase casting, where it is located and secured with a screw on each side. The brass spraybar is assembled through the body and encircled by a barrel throttle linked to an external lever. This lever is coupled to a centrally pivoted exhaust flap to close the exhaust opening progressively with barrel rotation.

Two adjusting screws are fitted to the carburettor body. One acts as a stop for the barrel movement for location of the degree of slow speed opening. The other controls the opening of the air bleed hole leading directly into the throat of the intake. This opening is masked off by rotation of the barrel at “open” throttle setting and thus is effective as an air bleed only at low speed settings

Close up of production type carburettor with forward facing air bleed for slow speed setting

when the barrel opening uncovers the hole. The whole carburettor unit and its linkage is very well made and positive in action and adjustment. The needle valve is locked by a spring and serrated thimble "ratchet” action, is light to adjust but holds exact settings. The throttle arm is on the right hand side (the same side as the exhaust) and the needle on the left.

Summarising, an engine of the highest quality throughout which should establish a lead in "multi” R/C work throughout the world. Whilst the specific output of .09 B.H.P. per c.c. is not as high as that achieved by many racing glow motors, it must be remembered that this is produced at a comparatively modest r.p.m. figure— and a figure, incidentally, which is about the ideal for radio control or large stunt control line work. It is certainly the most powerful engine of its type we have received to date—and a real pleasure to handle.
